What is a phase IIa clinical trial?
A phase II clinical trial is the phase of testing to see whether or not a drug has any biological effect. The phase IIa trial is the phase in which it is determined what dosage of a drug should be given.
What are phase 2 a clinical trials?
Phase II clinical trial determines the effectiveness and safety of the candidate drug in patients suffering from the condition the new drug is designed to treat. The main question that is answered in phase II studies is: "What is the most effective dosage range and the drug safety within that range?" Phase II studies enroll 100 to 300 subjects, and depending upon the type of investigational drug and the condition it treats, the trial lasts anywhere from six months to two years. Phase 2 is sometimes further classified into 2a and 2b phases based on the type of trials: Phase 2a assesses the amount of drug to be given to the subject for optimal results. Phase 2b assesses the how well the drug works at the prescribed dosage levels. Know more about the phases involved in clinical trials: http://www.crocareers.in

What is the Room temperature for storing clinical trial drug?

It is important to consult the specific drug's storage requirements as they can vary. Storage conditions may also depend on factors such as humidity, light exposure, and specific drug formulations.
What are the various types of Clinical Trial Supplies Market?
The global clinical trial supplies market size is expected to register a high CAGR during the forecast period, 2021–2028. The growth of the market is attributed to the increasing number of prevalence in clinical trials and increasing complexities of drug testing.
How does a pharmaceutical company invest in research and experimental studies?
These organizations are completely involved in drug manufacturing processes along with the drug’s clinical trials and phases, drug launch in the market, and its commercialization. Pharmaceutical invests in the research and experimental studies for the drug innovation and once the designing of the drug is finalized, they are often outsourced to the contract manufacturing organizations to manufacture the drug and undergo clinical trials and finally commercialize the drug.
What are some of the types of clinical trial designs?
Clinical study design is the formulation of trials and experiments in medical and epidemiological research. Many of the considerations here are shared under the more general topic of design of experiments but there can be others, in particular related to patient confidentiality and ethics.
What are the different phases of a clinical trial?
Clinical trials will generally have three or four phases. Phase 1 is a safety trial where a small number of healthy volunteers are given the treatment to see whether there are any serious side effects. If this is successful, then researchers will proceed to phase 2, testing a larger sample of people in order to discover how effective the treatment is and the best way to administer it. Phase 3 will often involve many thousands of patients, some receiving the new treatment while others have the current standard treatment, so that it can be established whether the new one is really better. A phase 4 trial may follow after a drug has been licensed.

Stakeholders in clinical trials?

What are importance of biostatistics in clinical research?
Statistics in clinical research is collecting and organizing numerical and clinical data obtained from the study sites and analyzing and interpreting it to verify the results of the trials and decide if it is was a success and if the drug is fit for human consumption. Using statistics helps in reasonable prediction of the effects of the drug on humans, even though the individual responses to the drug vary from person to person. Statistics plays a central role in the entire process of clinical trial from planning, conduct, interim analysis, final analysis and reporting.
